So instead of screwing around with trying to re-position the MAF - I just put the stock box back on this morning - and cleaned the MAF again for good measure - and took it for a drive. This resolved the struggling in low RPM I was describing - in other words, a lot more acceleration with a lot less accelerator. Seems like this would address my MPG and general sluggishness issue I described. Stands to reason as those two issues seemed to appear about the time I installed the HAI.
But the RPM jumping/bogging down still persists. Same conditions: at idle, after deceleration, transmission engaged, under load of AC.
I'm going to install the fuel filter first, test, then install O2 sensor, test. Just to isolate them so if one of them works, I'll know which one. (not sure if these will address issue but I have them so I'm going to use them). Anything I else I should try? Does anyone think I'm still looking at a bad MAF?
